Optimizing Liquid Manure Management: Exploring Nitrification Inhibitors in Ontario
Finch, ON|Feb 7, 2023
Hi I am from Ontario and we are thinking about using nitrification inhibitors in our liquid manure. What products are out there to use. When should we put it in the pit?
Thank you.

Take a look at other technology that doesn’t kill the enzymes/bacteria in the manure and soil. Those are very short lived and bank on the soil temperatures so they don’t rebound in populations. Nitrapyrin, NBPT and Those types of stabilizers have the same mode of action. They don’t just kill the bad but the good as well. University of Wisconsin, North American Manure Expo did a webinar on this very topic and research showed Instinct works sometimes and most often not from research in 2013. This is why they want the instinct used when temp are below 50 degrees or lower. I worked with instinct for over 30 years. Remember that they are starting to find theses chemicals in the rivers and don’t stay in the fields as well.
So I spent 20 years with Dow working with nitropiren N-Serve or instinct in manure. Very effective nitrogen stabilizer that showed very good results when incorporated in top two inches. If not incorporated it was very inconsistent. It also showed better with fall applications versus spring.
Those urea’s inhibitors we tried were better with surface spring applications and not great if manure was incorporated
Do you have more specific questions on types or how specific products work as a nitrification inhibitor? Let know know the products and I can break everything down for you. Thanks Dave
I can help you with that information. What are you looking at currently as a nitrification inhibitor? You can use the ones the kill the microbes and enzymes in the soil or the ones that actually connect to the nitrogen molecules like the CEC’s in the soil. The ones that kill microbes and enzymes are short lived in the manure and only last 10-14 days. They bank on soils below 50 degrees to not regenerate. Take a look at Triune that actually connects to the NH4 ammonium molecule and creates a slow release. Also reduces gases and disperses the solids in the pit or lagoon. I can be reached at dave@agrotechusa.com to discuss the different types of protection for nitrogen and other nutrients. Thanks
